Treatment of Linum album cell cultures with 10 μM salicylic acid (SA) for 3 days improved podophyllotoxin (PTOX) production up to 333 μg/g dry weight (DW): over three times that of the control cultures. qPCR analyses showed that in SA-treated cells, the expression of the genes coding for phenylalanine ammonia-lyase (PAL), cinnamoyl-CoA reductase (CCR) and(More)
Podophyllotoxin (PTOX) is a naturally occurring phenolic compound isolated as an active anti-tumor agent. The stimulatory influence of light on the formation of phenolic compounds has been reported, but the molecular mechanism underlying the effect of light on the expression of genes involved in phenolic biosynthesis, especially of lignans, is still not(More)
CONTEXT Suspension cultures of Linum album Kotschy ex Boiss. (Linaceae) accumulate podophyllotoxin (an anticancer agent) and could therefore serve as an alternative source of this important aryltetralin lactone lignan. OBJECTIVE The present work compared four podophyllotoxin extraction methods and optimization of the best one by using single factor(More)
The aim of this study was isolation and characterization of a crude oil degrader and biosurfactant-producing bacterium, along with optimization of conditions for crude oil degradation. Among 11 isolates, 5 were able to emulsify crude oil in Minimal Salt Medium (MSM) among which one isolate, named KA1, showed the highest potency for growth rate and(More)
Recent investigations have demonstrated that normobaric hyperoxia induces neuroprotection against ischemic injury. The aim of study was to determine the survey of HO (hyperoxia) preconditioning on brain lipidome.The animals were assigned into three groups, the first experimental group was exposed to 95% inspired HO for 4 h /day for six consecutive days. The(More)
Biosurfactans are amphiphilic compounds synthesized by a wide group of microorganisms and tend to interact with surfaces of different polarities. In the present study we purified and characterized a biosurfactant produced by Dietzia cinnamea KA-1 when cultured by n-hexadecane as sole carbon source. The crude biosurfactant was extracted with ethyl acetate(More)
The food industry is in a constant search for new technologies to improve the commercial sterilization process of agricultural commodities. Plasma treatment may offer a novel and efficient method for pesticide removal from agricultural product surfaces. To study the proposed technique of plasma food treatment, the degradation behavior of diazinon(More)
